Since i lost the majority of mine, with the leaking hose, i thought i would drain the radiator and replace. Now I am finding the HD is mostly red, what I ordered is red anyway. I have researched and found confusing information.
Mine was green EG(ETHYLENE GLYCOL) and the red is also EG Recommended for Cummins., i know some will be left in the system even as after the draining. My question is will it cause any problem to mix the two., i purchased Peak fleet guard.

I don't know what type of coach you have, but regardless, would not know what to suggest on this anyway.

I thought that maybe you could call this RV center, they look like they are about the closet to you. If the service department can not answer that type of simple question for you, then maybe they would not be worth visiting... Just a thought.

Yours, like mine, probably had Fleetguard ES Compleat PG coolant, which is propylene glycol and is green. I just had my coolant drained, system flushed and refilled with ES Compleat OAT which is the extended life OAT coolant that needs no SCA's and should last years. Final Charge is another popular OAT coolant that many people use. Both of these coolants are red.

According to Gary (Spike) on the Cummins forum, mixing different types of coolants is not a good idea.

Fleetguard (Red/Pink), Final Charge, etc. is what you want for your Cummins. The little bit that is left in the system should not hurt anything once it all gets mixed together.

Good Luck!

Just thinking about your situation a little bit more, if your radiator is already empty more or less, fill it up with water, run it for 20 minutes and drain it. This would ensure you got everything out, and only add about 30 minutes onto your project, also would not hurt to flush out system. Then you could refill with any of the RED radiator fluids. Its an extra step, but if it will set your mind at ease, might be worth doing.

Final Charge is red (made by Peak) and ES Compleat OAT is red and made by Fleetguard (Cummins). Peak also makes Fleet Charge which is pink but it is SCA premix and not an OAT coolant.

The color of antifreeze doesn't tell you what it is. You have to read the jug. Some will even tell you that is it compatible with all solutions of antifreeze.

I wouldn't get to hung up on the colors. Ive seen green,red ,blue ,orange and some colors between. The thing is whether you want the newer extended life coolants which will perform longer or conventional which require monitoring for protection. Its not really the freezing were worrying about but the additive packs. the organic extended life coolant will not deplete nearly as fast. Most truck fleet operators have made the switch to ELC of some type. Both cat and cummins have there own as well as other brands. Some coolant filters come with a sca additive pack built in. If you switch to ELC you buy a coolant filter that is empty and contains no supplemental additive pack. Hope this doesn't sound confusing.

What I have looked at has the SCA , i am concerned now about the filter, where is it located? I have not kept up to par on antifreeze. The auto parts recommend Peak fleet guard. With sca, where is the filter located, if I have one?
